yeah, the licenses and the build stuff seemed the biggest changes to me to. > I believe we can run a test of Ganglia using apr-0.9.5 on several > platforms to see how we're doing.

It seems to fix real problems for some people (bugzilla #87).

Another reason why I would go directly to 0.9.7. Not enough testers on to few platforms. > We wouldn't have to have a release out the door without properly > testing it under most OS/archs. > We did last time :-) And it works pretty well. Doing a 3.0.3 with apr-0.9.7 does not sound a big risk to me.
